Jonathan Zhang d9a6afe1a4 mb/ocp/monolake: use VPD data to configure FSP UPD
Summary:
This patch calls monolake board specific function to query
settings stored in VPD binary blob to configure FSP UPD
variable HyperThreading.

Test Plan:
* Build an OCP MonoLake coreboot image, run following command
to initialize RW_VPD and insert HyperThreading key:
vpd -f build/coreboot.rom -O -i RW_VPD -s 'HyperThreading=0'
* Flash the image to MonoLake, boot and observe following
message in boot log:
Detected 16 CPU threads

If RW_VPD partition does not exist, or if HyperThreading
key/value pair does not exist, the boot log has:
Detected 32 CPU threads
